I have a virus. A bad one. Avira popped up. Windows defender and windows firewall popped up. It was also popping up those fake antivirus ads. Antimalware. It turned off my windows security center. I was doing a malwarebytes scan. It tried to abort it. Now, I can't get on the internet and when I reboot windows defender pops up with this every time trojan:win32/alureon.bt. I also tried to do a system restore. It would not let me. Thanks in advance for the help.

Open task manager (Ctrl + alt + delete) and attempt to end wscsvc32.exe and/or wow64main.exe. Even if it doesn't successfully end the process, lets start out with Malwarebytes.

(If you cannot access the internet on the infected computer, download the setup files, and the most recent definition updates to a flash drive on a clean computer with internet access and transfer them over to the infected machine)

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it.

  • Before saving any of your security programs, rename them first. For example, before you save Malwarebytes', rename it to something like MBblah.exe and then click on Save and save it to your desktop. Same thing after you install it. Before running it, rename the main executable file first

    Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

    If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run..
  • Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here or here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.
For a complete visual tutorial of MBAM, see http://thespykiller.co.uk/index.php/topic,5946.0.html

Thank you for your help with this.

I went to end task on the wscsvc32.exe. It was not there. The scan you requested is below.

However, I ran a malwarebytes scan when the virus was attacking, and wscsvc.exe was there. The 32 was not listed. There were also: worms auto run, rogue.link, rootkit.tdss, trojan fake alerts, spyware passwords.

Would you like to see that log?

I also did a scan in safe mode, that included some of those. Would you like to see that log?

I am sorry to inform you that TDSS is a nasty rootkit. And therefore I must inform you that

These items are part of a very nasty rootkit.

IMPORTANT NOTE: One or more of the identified infections was related to a rootkit component. Rootkits and backdoor Trojan are very dangerous because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.

If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the rootkit was identified and removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because the rootkit has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

? "When should I re-format? How should I reinstall?"
? "Help: I Got Hacked. Now What Do I Do?"
? "Where to draw the line? When to recommend a format and reinstall?"

Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful.

Let me know how you wish to proceed.

Thank you. I will wipe and reload. What is safe to take off? Can I take off all of my music? This doesn't affect the other computers on the my network? I haven't had any viruses and now I have had 2 bad ones in the last month. What can I do to prevent this from happening again? I kept everything updated.

Be warned, I am going to post a lot of information :thumbsup:

These links include step-by-step instructions with screenshots:Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, personal data files and photos. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or .html files because they may be infected by malwareware appending itself to the executable. Some types of malware may even disguise itself by adding and hiding its extension to the existing extension of files so be sure you look closely at the full file name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

Don't forget you will have to go to Microsoft Update and apply all Windows security patches after reformatting.
Also see How to keep your Windows XP activation after clean install.

Note: If your using an IBM, HP, Compaq or Dell machine, you may not have an original XP CD Disk. By policy Microsoft no longer allows OEM manufactures to include the original Windows XP CD-ROM on computers sold with Windows preinstalled. Instead, most computers manufactured and sold by OEM vendors come with a vendor-specific Recovery Disk or Recovery Partition for performing a clean "factory restore" that will reformat your hard drive, remove all data and restore the computer to the state it was in when you first purchased it. See Technology Advisory Recovery Media

If you need additional assistance with reformatting, you can start a new topic in the Windows XP Home and Professional forum. If you don't get a reply, please send me a PM and I will get someone to take a look.

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:If using Windows Vista, please refer to:The other computers on your network should be safe, but it would be advised to scan them all with Malwarebytes.

For security, you basically need, an Anti-Virus program (with active monitoring), firewall, some on demand anti-malware scanners and a few other programs. My list would include
  • Avira AntiVir as my AV
  • Malwarebytes and SUPERAntiSpyware as on demand malware scanners
  • SpywareBlaster (the download link is in my sig) as a way to prevent infection in the first place
  • Comodo firewall (note: if using any other AntiVirus program, be sure to ONLY install the firewall from comodo, you will be prompted during installation)
